He moved straight landward through the cottonwoods, followed by the men in single file, but halted them while the rear was still discernible in the green tangle. Presently they unslung carbines, and I distinctly heard galloping. It was not far beyond the cottonwoods. The Yankees were after us. Suddenly it ceased. Over yonder, shoreward in the thicket, came a sharp command and then a second, and then, right on the front of the jungle, at the water's edge, the shots began to puff and crack, and the yellow river out here around the boat to spit!--spit!--in wicked white splashes. Every second their number grew. Behind me Quinn and his men stole away. But orders are orders and I had no choice but to watch the boat. The man in the stern had his back to me, and no face among the other five did I know. They were fast getting away, but the splashes came thick and close and presently one ball found its mark. The man at the stern hurriedly changed places with an oarsman; and as the relieved rower took his new seat he turned slowly upon his face as if in mortal pain, and I saw that the fresh hand at the oar was the brother of Major Harper. Just as I made the discovery "Boom!" said my small dust-cloud across the river, and "hurry-hurry-hurry-hurry-hurry-hurry-hurry--" like a train on a trestle-work--"boom!"--a shell left its gray track in the still air over the skiff and burst in the tops of the cottonwoods. The green thicket grew pale with the bomb's white smoke, yet "crack! crack!" and "spit! spit!" persisted the blue-coats' rifles. "Boom!" said again the field-piece on yonder side the water. Its shell came rattling through the air to burst on this side, out of the flashing and cracking of rifles and the sulphurous bomb smoke arose cries of men getting mangled, and I whimpered and gnawed my lips for joy, and I watched the boat, but no second shot came aboard, and--"Boom!--hurry-hurry-hurry- hurry"--ah! the frightful skill of it! A third shell tore the cottonwoods, its smoke slowly broadened out, a Federal bugle beyond the thicket sounded the Rally, and the cracking of carbines ceased. We went on in silence. Startled and distressed, I pondered. What was her new purpose, that she should ask, or even accept, such a favor as this from Ned Ferry; a favor which, within an hour, the whole command would know he had granted? Was this a trifle, which only the Gholson-like smallness of my soul made spectral? The first time I had ever seen Ferry with any of his followers about him, was he not on Charlotte's gray, now, unluckily, beyond reach, at Wiggins? Ah, yes; but Beauty lending a horse to speed Valor was one thing; Valor unhorsing himself to speed Beauty--oh, how different! What was the all-subordinating need? "Yes, I think I do; I think--" On the great banyan trees in the garden, and on every palm, torpid vultures sit in the sun, awaiting the meal that will come with the next funeral procession. "Yes. But how much is this?" “What?” “I wish your buddies and that-there Whiteside would do as much, then.” One great article of manufacture and export, however, down to this period, continued to be that of our woollens. To guard this manufacture many Acts had been passed at different times, prohibiting the exportation of the raw material. Immediately after the Revolution a fresh Act of this kind was passed, and such was the jealousy even of the Irish and of our American colonies weaving woollen cloths, that, in 1689, an Act was passed prohibiting the exportation of wool or woollen goods from Ireland or our plantations to any country except England. Having taken measures thus to confine as much as possible the profit of the woollen manufacture to England, the next year, which saw all protecting duties taken off corn, saw also leave given for the exportation of woollen cloths duty-free from England to any part of the world. Sir William Davenant estimates the value of the yearly growth of wool in England at this time at about ￡2,000,000, and the value of its woollen manufactures at ￡8,000,000. He calculates that one-fourth of this amount was exported. In 1738 Mr. John Kay invented the mode of casting the shuttle by what is called a "picking-peg," by which means the weaver was enabled to weave cloths of any width, and throw off twice the quantity in the same time. In 1758 the Leeds Cloth Hall was erected, and, about twenty years afterwards, a hall for white cloths. Si and Shorty strolled up to the young Irishmen, who were standing on the ground near their car. They were very plainly recent arrivals, for they still wore the characteristic clothes of the Emerald Isle, and after a little conversation with them Shorty produced his bottle and offered them a drink. The foreman had watched them suspiciously, and he came swaggering up, saying insolently: "I wonder whether Dr. Haenlingen knew him," Norma said. "The new one, I mean."
